A Specificationof Letters latent. Patented J n 22; 1920 Application area December 4, 1918,seria1 no. 265,293. Renewed April 24, 1920. Serial No. 376,425.

T 0 all whom it may concern: i v Be it known that we, JosnrH HERVE lioossnnnand ALEXIs Corn, subjectsof the King of Great Britain, residing at Trois Pistoles, county of Temiscouata', Province of Quebec, Dominion of Canada, have invented certain new' and usefulllmprovements in Flour-Mills, of which the following isaspecificationh r W a The present invention relates to improvements in flour mills in which the grain is ground andthe fineflour is separated from the bran by a" specially coiistructedrotary sifter. The grain is delivered from a hopper down into a movable shoe which spreads the grain evenly over a screw' whichfeeds the grinding plates. The meal as. it falls fromf,the grinding plates enters a chute which feeds it into the rotary sifter where the flour isseparatedfronithe bran, both falling into separate chutes. I

The main object ofthe invention is to provide preferably a manually operated grinding mill, of simple and du "able construction and particularly cheap, in order that it may be obtainable by all farmers or any household for making flour. for personal use. 7 V 1 Another object of the invention is to provide a grinding mill of such a character that the grain may be ground andthe flour separated from the bran in the same opera tion. I 4 E A further object of the present invention is to provide a machine of thi's character in which the grinding plates or stones may be moved close togetherto grind-a finer meal by pushing a pinwllichiis operated by a thumb screw nut.

A further object of the invention is to provide a sifter of cone shape whereby the fine meal will fall through the smaller portion of the sift er and the bran will naturally be carried down the larger end of the sifter and made to fall into a separate chute.

The invention will be better understood with the aid of the accompanying drawings in which:

Figure 1 is a side elevation of the machine.

F1g. 7 is a detail view of the shoe rocking attachment, the driving shaft being shown in section.

8 is a view of one end of the sifter.

F1g. 9 is a longitudinal section through one of the grinding plates, driving shaft and adjusting attachment.

Like numerals of reference indicate corresponding parts in, each figure.

in the drawings, 1 is a table and 2 are supporting standards suitably secured thereto. Onsaid table 1 is rigidly fixed a base, 3 adapted to receive the driving shaft 5% having intermediate thereof the feeding screw .5 and 011 which is mounted at one The companlon grinding plate 7 is rigidly fixed to the base 3 and the covering member 8, which latter is providedwith an elongated openlng 9 corresponding to the feeding screw 5; and 10 is an open ended casing or hopper upwardly projecting frolnsaid member 8. r

11 is ahopper secured above said casing or hopper 10, by the arms .12; and 13 is a sliding plate for controlling the grain feeding.

Below said hopper 11 is provided a shoe 14 which is pivotally secured on the bracket 15,; and 16 is an arm which isconnected at one end to said shoe 14, the lower end being forked to engage an eccentric 17 which Is mounted on said driving shaft 4. ,The arm 16 is pivotally connected intermediate of; its length to a lug 18 projecting-from 1 said bracket 15, whereby the eccentric will cause said arm 16 to swing from one side to the other, thus imparting'a to and fro movement to the shoe with the result that the grain will be evenly distributed to the feeding screw.

The driving shaft l is suitably journaled 1n bearings provided in the base 3 and the member 8, said shaft being provided at one end with a reduced portion 19 forming a shoulder; and 20 is a collar abutting against the bearings provided on the base 3 and member 8, said collar being provided with ball bearings abutting against the shoulder on said shaft 4; thus lessening considerably the friction. On the reduced portion 19 of shaft 4 are rigidly mounted a small pulley 21, a fly wheel 22 having a handle 23, and

a driving pulley 24 to drive the machine by any motive power should it be-found more epnr nie 7.

'At the opposite end of said shaft 4:, is rigidly mounted a supplementary crank handle 25, so that two persons may operate the machine if required.

7 The shaft 4:, at this endis provided with a longitudinal bore or socket 26 and 27 is a slot formed transversely through the shaft and'communicating with said bore 26. 28

is a collar slidably mounted on said shaft adjacent said slot 27 and the movable grinding'plate fi, and is provided with a central transverse slot 29. 30 is a grinding member adapted to engage the SlOt '29 in said collar 28 and slidablewithin the slot 27. KTllG said guiding member 30 is provided with a hole3ll' 32 is a pin movable in the bore 26 and fitting at one end in the hole 31 in said guiding member 30. The other end of said pin projects outward from said bore 26 and is operatedby the-threaded nut '33 which is provided with the wings 3 4Aand engages the threaded portion 35 on the outer end of said'shaft 4:. It Will'readily be understood that on -turning' said nut 33 in the proper direction, the-pin sewer be pushed forward, thus adjusting the movable grindingplate 6 against the fixed plate 7, so that the meal will be ground finer. a coarser meal it is necessary tounscrew tlie 11111333. p

The grain when grinding plates 6 and 7 passes through the funnel shaped chute 36 and falls into the rotatable sitter-"37 mounted on the shaft 38 which is journaled in suitable bearin s in the casing39 which'is preferably securec under the table 1. The said casing is provided with a ifiour'chute 4E0 projecting below the said sifter 37.; andl is a bran chute adjacent Jsaid flour chute and projecting below saidsifter, at-one'end thereof."

It will'thus be seen that the finer meal or flour For obtaining crushed between the 7 entering the smaller portion of the sifter willnaturally be divided or sorted from the a coarser meallor bran according .to its ability to. pass through the meshes of the sieve,
